Kusto 按聚合排序，如计数

Question

我是 Kusto/KQL 的新手，但在 T-SQL 方面经验丰富。我正在尝试获取异常列表，按类型对它们进行分组，添加计数，然后按该计数降序排列。在 SQL 中它将是：

SELECT Type, COUNT(Type)
FROM exceptions
GROUP BY Type
ORDER BY COUNT(Type) Desc

除了那类以外，我什么都做到了。

exceptions
| summarize count() by type

我无法弄清楚如何按聚合排序。我试过了| sort by count() desc，| sort by count() by type desc，| as c | sort by c desc，| extend c = summarize count() by type | sort by c desc

Answer 1

聚合的默认列名称count()是count_，因此：

exceptions
| summarize count() by type
| sort by count_ desc

或者，明确命名该列：

exceptions
| summarize CountExceptions = count() by type
| sort by CountExceptions desc
